1. List some specific adaptations that plants have to:

a. Reproduce:

· Pollen grain -male; gametophyte - contains sperm.

· Ovule - female gametophyte - contains the ovule.

· Stamen - Male reproductive organ of flower.

Pistil - Female reproductive organ. Flower

List some specific adaptations that plants have to:

a. Spread

Seed:

A

fruit provides protection for seeds and helps in seed dispersal.

Fruits

aids in the spread of seeds as animals eat fruit, pass through digestive

track, spreads as the animal wanders.

1. List some
specific adaptations that plants have to:

a. Attract

Pollinators:

Pollination

= transfer of pollen grains from anther to stigma.

Pollen

can be carried by wind, water or animals.

Wind-pollinated

produces a large amount of pollen due to wide dispersal.

2. Be able
to label the parts of a flower as discussed in class.

#1 Anther - structure in which

pollen grains develop.

#2

Filament - small stalk which supports each anther.

#3

Petal - colored structures which help to attract insects for pollination.

#4

Sepals - structures which protect the bud as it is developing.

#5

Receptacle - structure at the base of flower which holds all flower parts.

#6

Stigma - top area of the pistil where pollen grains attach and germinate.

#7

Style - tube down which the pollen tube grows as it moves towards the ovary.

#8

Ovary - structure containing the unfertilized seeds.

Male - Stamen - #1 and #2

Female - Pistil - #6, #7, and

#8

2. What is
the botanical definition of a fruit?

The ripened ovary of a flower. Provides protection for

seeds and helps in seed dispersal. Anything that has a seed in it, in science any plant that bears a seed in

it is a Fruit!

Why are plants important to
our planet? (4 reasons)

· provide food

· convert carbon dioxide into oxygen

· fertilize soil naturally

· can be used for medicines

5. What is the difference
between an angiosperm and a gymnosperm?

· Angiosperms protect seeds

· Gymnosperms don't have fruit enclosing seeds.

6. Discuss the relationship between insects and plants.

The both benefit from each other. The flowers use their colors to attract the insect. The insect gets the plants nectar while the insect fertilizes the plant.

7. What exactly is DNA and why is it important in
living things?

It is the hereditary material in humans and

almost all other organs. It holds the genetic information blueprint of a cell.Its important because it gives is the blueprint for life in every cell in our bodies.

Why is DNA a
more reliable source of identification than finger prints?

DNA is unique to the individual cant be altered cane be traced through genetics, finger-prints are based on judgement interpretaion

Describe the general structure of a DNA molecule?

The structure of DNA is illustrated by a right handed double helix, with about 10 nucleotide pairs per helical turn.

10. Where is DNA located within a cell?

· DNA is located within the nucleus of a cell

Describe a trajectory of evolutionary development in the animal kingdom:

o Porifera- sponges- specialized cells

o Cnideria- jellyfish- stinging cells defense mechanism

o Platyhelminthes- segmentation

o Mollusca- muscular foot for movement

o Annelida- well developed brain and sensory organs

o Arthropoda- external exoskeleton

o Chordates- humans, fish, amphibians, birds- skeletons of

bones or cartilae, well developed hearts

A) Explain with at least 5 specific
examples, evidence of climate change that has been reported in south Texas:

· Hotter temperatures

· Drier climates

· Coral Reefs die off due to increasingly hot temperatures.

· Rapid range change has been reported for migratory birds

· Water quality going down

If a parent questions you
regarding this topic, what resources will you refer them?

An Inconvinient Truth, Al Gore

Books on the Climate change of south Texas

Students may wonder what they can do to affect change. What will you suggest? Provide at least 5
different strategies that, practiced on a large scale, can impact this problem.

· Recycle waste

· Walk more instead of driving.

· Use energy efficient light bulbs

· Turn off all electric items when not using them

· Plant trees

· Use less hot water

We dissected several specimens. Describe how you would use a similar dissection exercise in an elementary classroom that is learner-centered,
knowledge-centered, assessment-centered and community centered. Be specific in your description and make sure that all four pillars of the How People Learn framework are addressed in
order to receive full credit

For most students who live in the corpus christi area and it’s

surroundings, most would have some type of past experience with the sand

dollar. In the learning process

the students who have no prior knowledge of sand dollars will develop information

through a hands on learning experience dissection of sand dollars. Come up with certain points students

may already know and have them posted for students to see during the

dissection. Then, go over briefly

with the students actual parts of a sand dollar and why those parts are

significant. Next, let the

students in groups of about four students each get a sand dollar for

dissection. Have students describe

the characteristics within their groups.

Make sure everyone gets a chance to share something they

experienced. As a class go over

with the class what they learned maybe one person from each group could share

something they learned. Have

students go home and explain to the parents what was experienced in class. It would be good to ask parents when

they first came across a sand dollar and what their experiences with it were!

1. Science
is not tested until 5th grade. Therefore, 38% of Texas teachers
admit that they do not include science in the curriculum, spending more time on
TAKS tested areas such as reading and math. Describe how you could include
science in the reading and/or math curriculum. Use a specific lesson and
describe how you would teach it. Also, include the four elements of the How
People Learn framework in your example. Make sure that your lesson addresses
TEKS content areas. You will be given a copy of the science TEKS for grades
K-6.

1. Describe a current area of interest in science and how you could teach this area of interest to an elementary classroom. You must include 1) specific, hands-on, minds-on activity; 2) TEKS that are addressed, and 3) the four elements of How People Learn. Note that this must be something
that was NOT done in class OR for Family Science. The more original and interesting, the more points may be awarded.
